FORESTED-LAND CIRCULATION [MODEL] (e) Biotic pump of atmospheric moisture: transpiration fluxes regulated by natural forests exceed oceanic evaporation fluxes to the degree when the arising oceanto- land fluxes of moist air become large enough to compensate losses of water to runoff in the entire river basin.

[MODEL] Surface heating on the equatorial zone produces strong upwellings of air. Rising air cools and looses moisture, making these rainy areas First, let’s observe and understand global atmospheric circulation ...when the dry air falls in the other extreme of the Hadley cells it warms up and takes moisture from the surface... making these dry areas The Hadley circulation transports heat from the equator to higher latitudes, and explains the trade winds near the surface, which transport moisture from the ocean to the Amazon Diagram source: internet material

DESERT CIRCULATION [MODEL] (a) Deserts: evaporation on land is close to zero, so the low level air moves from land to the ocean year round, thus "locking" the desert for moisture. Makarieva A.
